Objectives:
This study aimed to investigate whether a history of loop electrosurgical excision procedure (i.e., conisation) affects obstetric and neonatal outcomes.
Methods:
A retrospective cohort study was carried out in Västernorrland county, Sweden. 57 nulliparous women with singleton pregnancies and previous conisation were compared with 100 age-matched pregnant controls without history of conisation.
Results:
There was significantly lower gestational age by delivery (p = 0.036), however, the premature delivery rate was not different. Caesarean section was also less frequent (OR: 0.29, 95% CI: 0.081-1.04, p = 0.047) in the conisation group than those in the control group. There were no differences in neonatal outcomes.
Conclusions:
Previous conisation does not affect the risk of prematurity or cervical dilatation during the first stage of labour. Women with history of conisation had a lower rate of caesarean section, and lower gestational age by delivery.
